Table REF  displays accuracy on the RVL-CDIP test set as reported by prior work, as well as the scores achieved by us.
Table REF  also displays accuracy scores on our new RVL-CDIP-N test set.
First, we note that we achieve in-domain RVL-CDIP test scores that are close to the reported scores, with the exception of LayoutLMv2.
One difference between our setup and the LayoutLMv2 setup used in [1]} is the OCR engine used: we used the open-source Tesseract library whereas [1]} used a proprietary Microsoft Azure OCR model. In other words, OCR quality may have impacted our trained LayoutLMv2 model.
